.' 'The present 'invention'relates to an auto-' on a member extending along the pipe 85 matic scale for weighing goods, and the (13) through the whole length of the drum main feature of which consists in this that (17) and, ike the latter, is made of a sub-, the pressure (force of gravity) of the goods stance, such as vulcanized fiber, havin .the to be weighed isbalanced by a column of same longitudinal-ex ansion as that 0 the fl id, 4 fluid column.. The rum shaft (21), with 60 A form of execution of a scale according the weight scale bar"(23), rests. on a sup to the invention is shown on the drawing, port (24) whichin tiu'n rests on an elliph v a tical closed box, (25) filled. with a fluid the v Fig. -1 is a vertical section, with parts in expansion of which at temperature changes elevation of the scale,-and

Fig. 2. is a part-sectional plan view inthe pipe (13). The box rests on a thereof. i l l member (26) and between this member and A The scale comprises a frame (1) and a a member 28) secured to the bottom plate 15 tray (2) suspended on a supporting member (6) there is inserted an adjusting wedge (3) pointed at both ends, which tray IS (27) extendlng through the base of the 7 provided w itha bell-shaped guide 1) conframeand provlded outside the base with nected by three horizontal rods or hands an ad ustlng nut (29) by means of which (5) to three pins (7 secured to the bottom the dials and thus the scale can be ad usted 2 plate (6)" at equidistant points withrelation vertically. A valve is provided in the corresponds'to the moving of the zero point to each other and to the center of said plate. top of the .pipe (13), which valve, during fa' By this arrangement the tray is prevented transport, can be lockedin its closed-posifrom tilting if the goods be not laced centlon and, when the scale is in use, can opertrally on same. To counteract etrimental ate as a reversevalve and can close in case eifects of sudden shocks due to the gpods bethe fluid reaches the top of the pipe. A I ing suddenly placed upon the tray, t e upper ring (31) secured-to the bottom member 39 art of the supporting member (3) is slid- (1l) carr1es arms *P10V1d8d. with-rollers for able inthe lower part, a spring (8) being guiding the supporting member (3) in its interposedbetween the two parts to take up -vert1cal' movements: 30 the said shocks. The supporting member 7 I claim:

The cylindrical verdirectly coacts.

:40 tical part of the frame (1) is provided on 2. In a scale, a depressible platform; a

either side of the pipe (13) with glass plates vertical support having a pointed upper end (15) and. (16) and has inside a vertical drum whereon' the platform immediately rests;

(17) carrying the ,price' dials, the single and means for preventin tilting of the platprices being arranged in pairs of identical form, embodying a gui e within which the 45 rows on the dial and at such a distance'from support is disposed, and one or more hori-" each other that they may be read simultazontal members arranged below said support neously through both glass plates (15) and and connected to said guide.

The base of the frame (1) is pro- 3 .'In ascale, a depressible platform; a vided with a price dial, 18) according to vertical-support having a pointed upper 'end 5 which the drum 17) can e set by hand by whereon tie platform immediately rests;

to thesha-ft (21) of the drum'by means of form, embodying a bell-shaped guide within a bar (20). The weight indications- (22) which the support is disposed, and a pluare arranged on each side'of the. pipe (13) rality of diametrically-intersecting, horimeans of the him he (19) which is connected and means for preventing tilting of the platgulde.

7. A hydrostatic scale,

-zontal rods disposed below said support and connected to the lower edge of said 4.- In a scale, a depressible platform; and a vertical support'therefor, said support embodying upper and lower telescopically-arranged members and an ing spring, the upper member having, a pointed end whereon the platform immediatel rests.

5. X hydrostatic scale, comprising a depressible platform; for; an cxpansible and contractible receptacle whereon said support immediatelyrests, said support havin both ends pointed;

ta vertically-disposed, rising-and-falling col.

interior of said receptacle; and a graduated dial cooperative with the top of said column.

pressible platform; a vertical support therefor; an expansible-and-contractible receptacle whereon said support immediately rests; a vertically-disposed, rising-and-falling column of liquid communicating at its interposed cushion;

a vertical support thereof thecomprising a debottom with the interior float supported on the top of the liquid column and rovided with an index; and a dial across w ich said column moves having graduations with which the ihdex on said float directly coacts. v 45 v .8.- In a scale, a vertically-disposed rotary drum having rice indications marked thereon'in pairs 0 parallel vertical rows, the figures in the two rows of each pair being duplicates of each other, and the rows of each pair being spaced from each other; a fixed ring disposed coaxial with said drum and bearing price indications; means for rotating the drum'to set it with relation to said ring; and a vertical scale bar fixed with 5' 1 relation-to said scale and. adapted to occup a position opposite the sp'ace between the two rows of'a selected I air of rows.

9. A scale; accor ing to claim 8, in which a body, expansible and contractible under the influence of temperature changes, is provided to support directly both the drum and the vertical scale bar, and thereby adjust them in accordance with such changes;

10. A hydrostatic scale, comprising a depressible platform; a vertical support therefor; avertically-dispos ed, rising-and-falling column of liquid under the control of the platform; a vertically-disposed scale drum having graduations for coaction with the upper end of the liquid column; and an expansible and contractible bod for sup orting said drum and adjusting it vertical y in accordance with the expansion and contraction of the liquid column due to temperature changes. 1
